How can I save PowerPoint presentations from SlideShare for offline use?

I use Microsoft PowerPoint for studying and creating presentations, and sometimes I find useful presentations on SlideShare that I’d like to keep for offline reference.

What is the easiest way to save a SlideShare presentation in a format that can be opened or edited with Microsoft PowerPoint?

I came across ahttp:// https://slidesextract.com/ that can download presentations for offline use

Would this be a suitable option for getting a presentation and then opening it in PowerPoint?
